and also introduces the complications of wound infection and it again is technically more difficult. The only advantage appears to be that the patient is able to open his mouth. Zygomatic fractures are treated along traditional lines following methods such as the Gilles approach. The third section is on facial orthopaedics. The mangement of temporo-mandibular joint dysfunction due to hypermobility is of great practical interest with the advocation of implantation of a prosthesis or bone graft to ‘tighten’ up the joint, of which the success rate appears to be very high. The treatment of temporo-mandibular joint ankylosis by insertion of a metal implant again appears to be a good idea but with such a small number of cases it is early days to pass comment one way or the other. Bone grafting for increasing apical bone prior to orthodontics is questionable as orthodontists are agreed that new bone is laid down as pressure is applied to the teeth and therefore a bone graft would not be necessary. Perhaps, if surgical intervention is necessary, a Le Forte I osteotomy would be a better operation to perform. Simulography is a method that is suggested for the planning of osteotomies and is obviously sensible because the accuracy of the operation is increased but with such a deep excursion into the realms of physics, the process became very involved and difficult to follow. Certainly, the principle of rigid fixation of the fragments for a lengthier time would reduce the possibility of relapses and therefore give a higher success rate. The fourth section is on implantology. Here the idea of compression plates and pretension are very logical and sound but it does not overcome the most important problem in the failure of implants which is the epithelial proliferation and then infection tracking down the line of the implant via the oral stud. A success rate of 21.5 per cent over 15 months on a group of 70 patients is not very high, especially considering the relatively short period of time involved. Once again, one wonders whether more attention has been paid to the physics side of things rather than the biological. Large mandibular plates for the reconstruction of mandibles which have had to be reduced due to pathology have been around for some time and as time goes on they will be used more and more. The sub-section on antibiotics confirms what a lot of surgeons have believed for a long time, that prophylactic antibiotics do more good than harm especially as the time they are used for is usually very short.

Medicine,
This is a well-produced, up-to-date, monograph written by two authors who have made significant contributions to our present understanding of viral hepatitis. The result is a succinct and readable review of the viruses which cause hepatitis and the clinical syndromes which result from infection. The book is divided into ten short chapters covering aetiology, pathogenesis, epidemiology, acute hepatitis and an interesting chapter on extrahepatic manifestations. The hnal chapter on prevention is particularly comprehensive and should prove useful to both surgical operators and administrators alike. It says much for the authors that they have managed to include so much information in so few pages and yet are still able to indicate those areas where uncertainty or controversy exists. The book is well indexed and includes an extensive bibliography (450 refs) and is recommended not only to specialist workers in the field but also to all health care personnel whose work brings them into contact with this disease and it’s problems.

Self-Assessment Manual: Oral Surgery and Pathology. By BERTRAM COHEN, DAVID MASON and DAVID POSWILLO.London: Heinemann, 1978, pp. 72, with 96 colour and 16 black and white illustrations, f6.00. When three distinguished members of our profession combine to produce a book, we must have high hopes as to its value. In terms of academic accuracy, it cannot be faulted. Whether a dentist works in specialist hospital practice or in general practice most of the conditions illustrated might be seen at some time by the practitioner. The ability to recognise the uncommon not only increases a patient’s regard for the dentist, but will add to the interest of his daily work
